  • Some of you mentioned an "omega coil". I was interested in and began to search on the web. My search was not successfully.

    But I found a pdf file about search coils (very interesting):

    "omega coil"? How does it look like?

    • Underground?

      Hi Ivconic !

      Now you exploring underground....You are incredible !!!
      My TGS pcb,bi soon finished......

      • Hi Ivconic! Nice exploration! You're very famous! When I write on Google images "metal detector schematic", your name appears on PCB!

          Hi Aziz,
          Here :
          http://geotech.thunting.com/cgi-bin/...gnum/index.dat
          You will find the "magnum" metal detector.There is construction info about the omega coil.
          Basically the TX coil is like a big omega letter, then the RX is the size of the center loop of the omega and positioned to achieve nulling.
          regards,
          Fred.

Already robbered by some previous prospectors. only thing i founded there was borken skull. I collected fragments carefully and burried back on its place.
            Let it rest in piece. Amen.
            Hi Ivconic,

            Great!,
            you look good on this picture too

              Nice article.
              Omega coil or whatever called, is very nice for pinpointing.I made few so far.It is easy to apply faraday cage on it and even more easy to null it.
              Good job.

                Things couldnt be simplier;
                if you want your detector to go very deep - simply use it underground!
                Simply as that...

                  Main point of interenet is to allow anonymus person (like myself) to reach others arround globe.
                  But in this,our, hobby....it is better to stay totally unknown..

                    I like this actor. Really. From Terminator and further. What was his name? Patrick...and something?
                    Not possible that i remind you on him!?

                      Hi,
                      It´s Robert Patrick.
                      Yes on the picture you sent IMHO you really ressemble him (or the contrary ).
                      From Terminator he was made of metling metal.Are you ? bad for detecting...
                      Regards
                      Fred.

                        ivkonic: "I opened it and spoted funny pcb, but descent populated with compnents... Coil is large and pretty well designed. Actually i mostly like coil design and plastic quality they used...But overalll - poor very poor performances..."

                        Coil you mentioned was obviously patented (see Azizs previous DeepTech link) by Mustafa Uzman, the seller of MD Atlantis Imperator on eBay.

                        Regarding HQ pots on your photos not to cheap made MD such Imperator?

                          • Thanks for the description and visualisation. I know now what omega coil is.
                            For all, who are interested on magnetic field strength distribution, see picture below. I should make more simulations in the future.

                                Hi Aziz
                                Interesting, congratulation, and hope usable in measurement not only programming toys.
                                But what is input parameters (how coil shape is influenced in visual xyz results?)?
                                What happen if you put third cold coil somewhere in field, can you to define it?
                                Thanks
